Packing of compressible granular materials
3D computer simulations and experiments are employed to study random packings of compressible spherical grains under external confining stress. In the rigid ball limit, we find a continuous transition in which the stress vanishes as (straight phi-straight phi(c))(beta), where straight phi is the (solid phase) volume density. The value of straight phi(c) depends on whether the grains interact vi...

چکیده این تحقیق " مواد درسی " را به عنوان یکی از بحث برانگیزترین موضوعات آموزش زبان تلقی کرده و درتلاش است به سه سوال عمده پاسخ دهد: 1) آیا بکارگیری جزوات گرداوری شده توسط گروهی از مدرسین تاثیر بسزایی در میزان توانش خواندن و درک متون انگلیسی دانشجویان پزشکی دارد؟ 2) آیا استفاده از مواد درسی اصلی( بین المللی )، توانش خواندن و درک متون انگلیسی دانشجویان پزشکی را به طور چشمگیری تحت تاثیر قرار م...
15 صفحه اولthe effect of authentic listening materials on the listening proficiency of efl learners in the intermediate level
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
15 صفحه اولTwo-dimensional packing in prolate granular materials.
We investigate the two-dimensional packing of extremely prolate (aspect ratio alpha=L/D>10) granular materials, comparing experiments with Monte Carlo simulations. The average packing fraction of particles with aspect ratio alpha=12 is 0.68+/-0.03. We quantify the orientational correlation of particles and find a correlation length of two particle lengths. The functional form of the orientation...
متن کاملNumerical Investigation on the Reference Crushing Stress of Granular Materials in Triaxial Compression Test
Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...
